The three fast charging technology on the market is used for the fast charging of mobile phones

One of the fast charging technologies: VOOC flash charge

There are two major ways to improve the charging speed: one is to increase the voltage and the two is to increase the current. Increasing the voltage will increase the amount of heat in the charging process, accelerate the aging of the battery and may bring security risks, so the actual effect is not good. In contrast, it is more realistic to improve the current. The VOOC flashover technology uses low voltage and high current mode to ensure the safety of the charging process.

The VOOC charge is charged for 5 minutes for 2 hours, and charging for 30 minutes can charge the phone's power from 0% to 75%.

High pass Quick Charge 2 technology is an upgraded version of Quick Charge 1 and uses a new specification. The charging speed is improved by increasing the current and voltage at the same time.

Three of fast charging technology: Pump Express Plus of the co generation Department

Pump Express, a new fast charging technology for the United States, is built into the power management integrated circuit of PMIC. Allows the charger to decide the initial voltage required for charging according to the current. The PMIC sends out the pulse current command to the charger through the USB Vbus. The charger changes the output voltage according to this instruction, and the voltage gradually increases to 5V, reaching the maximum charging current.
